Ed, who recently showed off a Drake-inspired needlepoint made for him by Taylor - thinks the 22-year-old's choice of hobbies make her seem old beyond her years.

He said: "I know she's 24 but she's a sort of middle-aged woman trapped in a 24 year old's body. She hangs out with her cat and sews things."

And Ed admitted he didn't make a gift in return for the canvas, which hangs on his wall.

Asked if he made anything for Taylor, he told TIME magazine: "No, but I'm not a very crafty sort of person. She's very crafty."

Meanwhile, the 23-year-old claimed his own "soul age" changes day to day, depending on what he is doing at the time.

He said: "My soul age differs from day to day. It can be 8 or 80. It just depends on what I'm doing.

"If I'm working it's usually pretty spot-on for work, but if I'm with my friends and the clock's off I'll go back to being young."

Ed announced the launch of the first interactive full-length music TV advert to promote his second album 'x'.

The follow up to his superb debut is currently number one on the iTunes chart in 65 countries just 24 hours after being released.

It will feature in the advert which will allow viewers to vote on which song from his new record he will perform in its entirety.

Ed said: "For me, this is a really cool way to show songs from the album that fans will have never seen performed in this way before.

"It gives my fans the chance to decide which songs from the new album they want to see most, their involvement is really important to me."

The track which receives the most votes via Twitter will premiere in the final advert break of The Big Bang Theory on E4, with the first section of the innovative two-part promo airing prior to the start of the show, featuring Ed explaining the idea and social voting mechanism.

During the programme, the amount of hashtag mentions across Twitter will be monitored in real time to determine which track Ed will perform.

Jack Melhuish, Marketing Director for Atlantic Records, said: "Ed's new album is a very special record.

"We wanted to find a way to reflect the strength of the songs in a more uninterrupted way than a standard TV ad.

"As well as harness the huge amount of social engagement that Ed is at the centre of to do something original and compelling "

The advert will also debut on Ed's YouTube channel, with the winning performance uploaded for his global audience to view the day after it has aired on TV.

Ed will also take to the stage at Glastonbury festival this week at Worthy Farm in Somerset.
